Consider your environment for both tech and size. For example, if you watch sports during the day under bright light situation you may consider mini LED technology over OLED, like the Sony Bravia 9 or Samsung. Size is immersive, for me a distance of 7 times the vertical screen height is the sweet spot, so size is dependent on your room and how far you sit from the TV. Of the choices you presented, you are at flagship level so IMO you cannot go wrong with any of those models. I do like dolby vision (dynamic control of brightness dependent on scene) and there is a ton of content that supports that format (Blu ray discs, Netflix, Apple +, Prime). Unfortunately Samsung does not support, so for me the Samsung would be out. After two years I am still smitten over my flagship Sony mini LED TV. One more thing you get with Sony is access to Sony Pictures Core, only available to Sony TV customers
https://electronics.sony.com/sony-pictures-core . It streams at 80MB/s (compared to Netflix at 20MB or Apple + at 30MB) which approaches 4K HDR Blu Ray disc quality (100MB/s). Additionaly, you get 10 or 15 credits (movies) with TV purchase depending upon model purchased.
